Pandulf IV of Capua

Pandulf IV of Capua (died 1050) was Prince of Capua from 1016 to 1022 (succeeding Pandulf II and preceding Pandulf V), from 1026 to 1038 (succeeding Pandulf V and preceding Guaimar), and from 1047 to 1050 (succeeding Guaimar and preceding Pandulf VI).

Biography
Pandulf was the cousin of Count Pandulf II of Capua, and he succeeded his cousin as Count in 1016. Pandulf was a supporter of the Byzantine Empire during the wars between the Byzantines, the Lombard princes, the Papal States, and the Holy Roman Empire in southern Italy during the 11th century, leading to his deposition during the Holy Roman Emperor Henry II's Italian campaign of 1022. The Count of Teano was made "Pandulf V", and Pandulf IV hired Rainulf Drengot's Norman mercenaries to restore him to power. In 1026, after an 18-month siege, Byzantine and Norman forces reconquered Capua and restored Pandulf IV to the throne. When Pandulf V fled to the court of Count Sergius IV of Naples, Pandulf IV laid siege to the city, but the Normans - fearing that Pandulf IV was becoming too strong - switched sides in 1029 and drove Pandulf IV back to Capua. In 1032, Pandulf IV conquered Gaeta, but he was again deposed by the Emperor in 1038 and forced to flee to the Byzantines, who imprisoned him rather than return to supporting him. Guaimar of Capua seized power, but, in 1042, Pandulf IV returned to Italy. In 1047, Holy Roman Emperor Henry III restored Pandulf to power after vassalizing the Normans, and Pandulf died in 1050.
